I'm satisfied with the job my clown pleco does. For the smallest of the pleco species,he does a great job. He doesn't bother other fish like siamese algae eaters are capable of. My Ottos are great plant and glass cleaners.

I guess you could try shrimp (cherry, amano, glass/ghost).They will eat algae and clean up the left over food, but, like said before, they will become snacks for the fish once they can fit them into their mouths.

I think a BN pleco or a bushy nose pleco or a clown pleco, would be good, but, I don't know if they would fit... otherwise, ottos are very nice for planted tanks,_________________Lifes short, so waste it wisely, and eat dessert first!!

Knowing that it is not an algae problem and that all you need is a bottom feeder to clean up any excess food left by the other inhabitants, a clown pleco is probably a best choice. Even if you do your water changes regularly it is always a plus to have a clown pleco as your bottom feeder. I own one not for its' beauty, although they have a nice color pattern,but for the job they do well. Algae doesn't mean there is a problem. It is a good thing when kept in check. Plecos and ottos do just that.
